THE CONNECTICUT AGRICULTURAL 



We conclude then that these anah^ses demonstrate that this 

 method of working is incompetent to give any clear notions as to 

 the quantity or even as to the kind of changes that go on in the 

 silo. This result was not unexpected, nevertheless, we regarded 

 the questions involved worthy of careful experimental study. 



The antiseptic quality of acids, especially of carbonic acid gas, 

 which has lately been demonstrated by Kolbe, is such as to lead 

 to the conclusion that no considerable amount of chemical change 

 or of loss of nutritive matters can go on in the well constructed 

 silo. Dr. Neale has, we believe, found furtlier experimental evi- 

 dence of that conclusion in recent investigations at the New Jer- 

 sey'Experiment Station. 



Beoai) Rock Farm Ensilage. 



A valuable contribution to the literature of Ensilage has been 

 recently made by Mr. Rowland Hazard, of Peace Dale, R. I., 

 President of the Washington County (R. I.) Agricultural Society. 



A sample of Mr. Hazard's ensilage was analyzed at the Station, 

 and the results are here given, together with Mr. Hazard's com- 

 ments, taken from a memorandum printed by him. 



The ensilage was made from corn " cut in September, after the 

 ears were well advanced," on the principle that " the first condi- 

 tion of success with a silo, is to have a good crop to put into it."

* Alcohol, was not positively proven to be present to the extent given, but the 

 figures are probably not far from correct. The amounts of both alcohol and 

 acetic acid may easily increase (or change) after the sample leaves the silo, during 

 its transportation or while it awaits the operations of analysis. There is no 

 probability that the ensilage as fed was so sour or so alcoholic as when analyzed. 

 In fact, the odor of ensilage fresh from the silo is, so far as the writer has had 

 opportunity to observe, much less acid than that which has been received at the 

 station for analysis.
